| GaAs HJ-FET L TO S BAND LOW NOISE AMPLIFIER (New Plastic Package) FEATURES * LOW COST MINIATURE PLASTIC PACKAGE (SOT-343) Noise Figure, NF (dB) 4 NE38018 NOISE FIGURE & ASSOCIATED GAIN vs. FREQUENCY VCE = 2 V, ID= 5 mA 25 20 GA 3 15 10 * HIGH ASSOCIATED GAIN: 14.5 dB typical at 2 GHz * LG = 0.6 m, WG = 800 m * TAPE & REEL PACKAGING 2 5 0 DESCRIPTION The NE38018 is a low cost gallium arsenide Hetero-Junction FET housed in a miniature (SOT-343) plastic surface mount package. The device is fabricated using ion implantation for improved RF and DC performance, reliability, and uniformity. Its low noise figure, high gain, small size and weight make it an ideal low noise medium power amplifier transistor in the 13 GHz frequency range. The NE38018 is suitable for GPS, PCS, WLAN, MMDS, and other commercial applications. NEC's stringent quality assurance and test procedures ensure the highest reliability and performance. 1 NF 0 0.5 1 2 3 4 5 6 7 8 910 Frequency, f (GHz) 18 Package SOT-343 Style ELECTRICAL CHARACTERISTICS (TA = 25C) PART NUMBER PACKAGE OUTLINE SYMBOL NF1 GA1 P1dB PARAMETERS AND CONDITIONS Noise Figure at VDS = 2 V, ID = 5 mA, f = 2 GHz Associated Gain at VDS = 2 V, ID = 5 mA, f = 2 GHz Output Power at 1 dB Gain Compression Point, f = 2 GHz VDS = 2 V, IDS = 15 mA VDS = 3 V, IDS = 30 mA Gain at P1dB, f = 2 GHz VDS = 2 V, IDS = 10 mA VDS = 3 V, IDS = 20 mA VDS = 2 V, IDS = 5 mA, f = 2 GHz Output IP3 at f = 2 GHz, f = 1 MHz, VDS = 3 V, IDS = 5 mA Saturated Drain Current at VDS = 2 V, VGS = 0 V Pinch Off Voltage at VDS = 2 V, ID = 100 A Transconductance at VDS = 2 V, ID = 5 mA Gate to Source Leakage Current at VGS = -3 V Thermal Resistance (Channel to Ambient) dBm dBm mA V mS A C/W 40 -0.1 50 UNITS dB dB dBm dBm 12.5 MIN NE38018 18 TYP 0.55 14.5 12 17 (V67) 18 (V68) 16.0 16.5 16.5 22 (V67) 23 (V68) 100 -0.8 80 1 833 20 170 -1.5 MAX 1.0 G1dB dB dB MAG O/P IP3 IDSS VP gm IGSO RTH(CH-A) Note: 1. Typical values of noise figures and associated gain are those obtained when 50% of the devices from a large number of lots were individually measured in a circuit with the input individually tuned to obtain the minimum value. Maximum values are criteria established on the production line as a "go-no-go" screening test with the fixture tuned for the "generic" type but not for each specimen.
